HERMAN F. HALBAGH, OF BALTIMORE, MARYLAND, ASSIGNOE OF ONE- HALF OF HISRIGHT TO HENRY H. FAUST, OF SAME PLACE.

BOOT AND SHOE HEEL TRIMMING MACHINE.

SPECIFICATION forming part of Letters Patent No. 232,180, datedSeptember 14, 1880.

Application filed May 31, 1880. (ModeL) To all whom it may concern:

Be it known that I, HERMAN F. HALBAGH, of the city of Baltimore, in thecounty of Baltimore and State of Maryland, have invented a new anduseful Improvement in Shoe and Boot Heel Trimming Machines, of which thefollowing is a full, clear, and exact description, reference being hadto the accompanying drawings, forming part thereof.

My invention relates to shoe and boot machinery; and its objects are,first, to shape a heel from the rough square leather to any desiredshape 5 and, second, to finish the heel, ready for the blacking andburnishing. I attain these objects by the mechanism illustrated in theaccompanying drawings, in which-- Figure 1 is an end view of the entiremachine. Fig. 2 is a side elevation of the same. Fig. 3 is a top View ofpart of the machine. Fig. 4. is an enlarged side view of the rotarycutter; and Fig. 5 is an enlarged sectional view of the friction-rollerand its eccentric shaft, hereinafter more fully described.

Similar letters of reference throughout the several views indicate likeparts.

A is the main frame, and carries the main shaft B, which is rotated bymeans of a crank, B, or a pulley. On the shaft B, and rotating with it,is the large gear-wheelO which operates the pinions G and C on shafts Dand D,

The frames E and E are alike in construction, and swing on shafts D andD on bearings Z l, between which are placed the pinions O and C onshafts D and D. On a shaft, 0, on one arm of frame E, is thechipping-wheel or rotary cutter e and small pulley c and on anotherarm'of frame E is an eccentric shaft, 0 which carries thefriction-roller e.

The frame E has a shaft similar to shaft (2, but which carries asand-paper wheel or' its equivalent, 6 (See Fig. 3.) On shafts D and D,and rotating with them, are the pulleys D and D and an endless beltpasses over each to the pulleys e 6 by which means the rotary cutter cand the sand-paper wheel or its equivalent c are rotated.

A screw, F, is placed on shaft B, and in its threads engage the levers fand f, having their fulcrums on the frames E and E at f 2 and frespectively. To levers f and f are hooked the rods 9 and 9, connectedat their lower ends to treadles h and h.

To main shaft B is fastened the disk I, provided with a slot, i, inwhich the wrist i is adjustable by means of a screw, d. A segment, K,swings on the stud k, screwed to a hub on the frame A. The lower end ofsaid segment K is provided with a slot, K, and through it projects thewrist i. The segment K operates the gear-wheel N, placed loosely onshaft n, which has its bearings in the main frame A.

To the gear-wheel N is fastened the disk N, provided with two notches, nand n Secured to the shaft n is the plate N provided with lugs and pinor, on which swings the lever a, which has one end engaged in one of thenotches n or a (a in the drawings,) and the other end is provided with aknob, a against which presses a spring placed between the knob 12. andplate N Figs. 2 and 3.

To shaft a is also secured the gear-wheel O, in a recess of the frame A,and to it is fastened by some well-known means the former 1?. Gearwheel0 operates gear-wheel O on shaft 0, which has its hearings on the mainframe A, and the one end is coupled by means of a universal joint, 0, toshaft 0 placed in the bearingp, and to the extreme end of said shaft 0is fastened by some device the shoe or boot with its rough heel to betrimmed.

The bearing 11 swings on its trunnions p and 12 between two lugs on theframe A, and has an arm, p projecting downward in a recess in frame A,(shown in dotted lines in Fig. 2,) and can be securely locked there by apin, 13, passing through the frame A and arm p Through a hub, a, on mainframe A passes a rod, a, provided on one end with a plate, a, and aroundthe rod to in the hollowed-out hub a is wound a spring pressing againsta collar on rod a, by which means the plate a is pressed against theheel of the shoe or boot placed on shaft 0 The operation of this machineis as follows: In order to place the shoe or boot on shaft 0 it isnecessary to remove the pin 12*, and the bearing 19, with its shaft 0,is then swung on its trunnions p and p upward at right angle, (theuniversal joint 0 allows this operation,)

2 aaaaieo which enables the operator to fasten the shoe or boot by meansof lastor other device to the shaft The bearing 2 is then swung in theposition again, as shown in Fig. 2, and the pin p is inserted, wherebythe bearing 19 is locked.

Partial rotation is given to the shoe or boot on shaft 0 by rotating theshaft B, by crank or pulley, which causes the segment K to oscillate onstud k by means of disk I, its wrist i being engaged in the slot K ofsegment K. The segment K transmits its motion to gear N, its disk N, andto plate N by having the lever a engaged in notch a of disk i The plateN transmits its partial rotation to shaft 1', gearwheel 0, and itsformer P. Gear-wheel 0 gives partially rotating motion to gear 0,whereby the shaft 0, and shaft 0 with its shoe or boot, are partiallyrotated.

For the first operation-that is, for the shaping of the heel by therotary cutter cit is necessary to throw the lever f out of contact withscrew F, by rod g and treadle h, while lever f remains in contact withsaid screw F. The latter, being rotated, causes the lever f, and therebythe frame E, to which it is fastened, the shaft D, the pinion 0, andpulley l) to move sidewjse, (to the left in Fig. 2,) which brings thefriction-roller 0 over the heelshaped former P and the cutter e to theheel to be trimmed to the shape of former P. Rotation is given to cuttere by pulley c and the endless belt passing over pulley D The pinion (l,placed between the two bearings Z l of frame E, is made very long, so asto allow sidewise movement without going out of gear with the gear wheelG on the shaft B. The frictionroller 0 is held against a straightextension of former P by means of a spring, '0, fastened to the mainframeA and the sliding frame E. The latter, now moving sidewise, causesthe friction-roller to followthe shape of the former P, and as thepartial rotation of the boot or shoe on shaft 0 is the same as of formerP, and the friction-roller c and rotary cutter c are on the sameswinging frame, thereby moving simultaneously sidewise, the heel to betrimmed attains the same shape as has the former. When thefriction-roller c arrives at the end of formerP the lever f stands atthe end of screw F, and moving up the incline f will cause a stop ofsidewise motion to the frame E and its accessories. By means of a springor weight (not shown in the drawings) attached to frame E or shaft D theparts which have made the sidewisemovement can be thrown back to theiroriginal position, as shown in Fig. 2. The relation ofthe partialrotation of the shoe or boot on shaft 0 to the cutter c is such that therotary cutter commences to trim on the edge of the flat part of theheel, around the curve of the heel, over to the other edge of the flatpart and back again.

Pressing on knob n will disengage lever a} from notch n whereby theplate N and shaft n cease to partially rotate, and consequently the shoeor boot on shaft 0 is brought to a stop until the lever 12 engages innotch '12, whereby a partial rotation in the opposite direction fromwhat had been obtained before will be given to the shoe or boot, whichmotion is necessary for the second operationthat is, the finishing ofthe heel with the sand-paper wheel, or its equivalent 0 The lever f isnow thrown in contact with screw F, (the leverfis held disengaged bytreadle 7b,) and the same movement is given to frame E and itsaccessories as had been given to frame E, described above. Thefriction-roller c on frame E will be moved over former P, whilewthesand-paper wheel or its equivalent 0 will finish the heel ready forblacking and burnishing.

For the different shaped formers a different oscillation is required,and is obtained by moving the adjustable wrist i, by means of screw 2'in or out in the sloti of disk I, and thereby in or out of slot K ofsegment K, whereby more or less oscillation of the segment K isobtained. An entire revolution can by this device be given to the bootor shoe on shaft 0 As shoe and boot heels vary in width, (for larger orsmaller shoes of the same pattern,) but retain the same curved shape, Ihave placed the friction-roller e on an eccentric shaft, 0 (see Fig. 5,)which can be turned in its hearing on frame E or E by a lever, 0 andfastened in any desired place by set-screw 0 This operation throws thefriction-roller e to or from the former P, and the rotary cutter c to orfrom the rough heel, whereby the same former P answers for trimmingheels of the same curved shape as former P, and also for trimming heelsto various widths.

2, The rotating shaft 13, with its screw F, in combination with thelever f and frame E, as and for the purpose specified.
